IL-17 is produced by RAR-related orphan receptor gamma t (RORγt)-expressing cells including Th17 cells, subsets of γδT cells and innate lymphoid cells (ILCs). The biological significance of IL-17-producing cells is well-studied in contexts of inflammation, autoimmunity and host defense against infection. While most of available studies in tumor immunity mainly focused on the role of T-bet-expressing cells, including cytotoxic CD8⁺ T cells and NK cells, and their exhaustion status, the role of IL-17-producing cells remains poorly understood. While IL-17-producing T-cells were shown to be anti-tumorigenic in adoptive T-cell therapy settings, mice deficient in type 17 genes suggest a protumorigenic potential of IL-17-producing cells. This review discusses the features of IL-17-producing cells, of both lymphocytic and myeloid origins, as well as their suggested pro- and/or anti-tumorigenic functions in an organ-dependent context. Potential therapeutic approaches targeting these cells in the tumor microenvironment will also be discussed.

We present the case of a 23-year-old man who suddenly collapsed during a physical altercation with his friends while in a drunken state. The post-mortem computed tomography (CT) with angiography revealed acute basal subarachnoid hemorrhage with rupture of the left middle cerebral artery. On autopsy, the head, face, mandible and neck showed multifocal hemorrhages with fracture of the hyoid bone, and the pathologic findings of the brain was consistent with CT findings. However, the vascular rupture site was not observed macroscopically. On histologic examination, a microscopic focal rupture was identified at the proximal portion of the middle cerebral artery, and possibility of arteriopathy was considered. This case illustrates that other parts of intracerebral arteries (other than the vertebral arteries) can be the culprit of rupture in the case of traumatic basal subarachnoid hemorrhage, and the post-mortem angiographic findings can be helpful in targeting the site of vascular injury. Furthermore, meticulous sampling of intracranial vessels could help find the vascular rupture site and identify any histologic findings suspicious of arteriopathy. Therefore, we suggest that post-mortem angiography can be an effective and adjunctive tool for a tailored approach in finding the vascular injury, and that histologic examination of both the intracranial and extracranial arteries be important to medicolegally ensure the death of traumatic basal subarachnoid hemorrhage and to examine presence of arteriopathy as a predisposing factor.

PURPOSE: This study analyzed a path through which factors influencing death anxiety in the community-dwelling elderly, assuming personal organismic factors and microsystemic factors based on the ecology model purported by Belsky (1980). METHODS: This study was performed with 189 elderly people. Data were collected through a self-report questionnaire. The data were analyzed using the SPSS and AMOS programs. RESULTS: The factors influencing death anxiety in the elderly were depression, family support, social network, and familism value, and the explanatory power of these variables was 22%. Death anxiety increased with higher depression, higher familism value, larger social network, and lower family support. Spiritual well-being and elderly discrimination experience had indirect effects on death anxiety, and these effects were mediated by depression. CONCLUSION: Depression, family support, social network, and familism value were found to influence death anxiety in the elderly, and the strongest effect came from depression. To reduce death anxiety in the elderly, it is important to improve their relationship with their family and friends. Moreover, support should be provided by establishing local systems, and intervention should be provided to alleviate depression.

OBJECTIVE: The aim of this study was to investigate the interpersonal violence (IPV) epidemiology and mortality according to the violence victim-perpetrator relationships. METHODS: A retrospective cross-sectional study was done using the comprehensive data of the emergency department (ED)-based Jeju Injury Surveillance System from all EDs in Jeju Island. The demographic characteristics of the victims, the types of perpetrators (spouse, family members, acquaintance, and stranger), injury characteristics and clinical outcomes from the injury were collected. The IPV epidemiology was reported by descriptive statistics. Multivariate Poisson regression was used to analyze the association between the mortality and violence victim-perpetrator relationships. RESULTS: Among the 23,508 violent injury patients enrolled from January 1, 2008, and December 31 of 2016, 19,879 (84.6%) were analyzed; 16 (0.08%) died at the ED. The types of perpetrators were the spouse (10.1%), family members (3.9%), acquaintances (43.4%), and strangers (42.7%). The mortality of the violence victims was increased significantly by the spouse (incidence rate ratio [IRR], 6.336; P=0.043) or family members (IRR, 11.089; P=0.016) compared to strangers. On the other hand, there was no difference between the acquaintances and strangers. CONCLUSION: The epidemiology and mortality of IPV were associated with the violence victim-perpetrator relationships. Therefore, it is necessary to develop and apply prevention programs considering these differences, particularly for intimidate/ family violence because of its high fatality.

PURPOSE: This study aimed to identify the factors that impact the intention of sexual abstinence among female college students. The approach was based on Ajzen's theory of planned behavior and the parent-adolescent communication of contextual factors. METHODS: A total of 189 female university students in the first to fourth grades at two universities in Honam region participated in the study. The collected data were analyzed using hierarchical stepwise multiple regression using SPSS 21.0. RESULTS: The major factor that influences the intention of sexual abstinence among female college students was attitudes toward sexual behavior (β=0.53, p<0.001). Other factors, in descending order of their impact, were subjective norms toward friends (β=0.25, p<0.001), experience of sexual intercourse (β=−0.19, p<0.001), and subjective norms toward parents (β=0.09, p=0.040). Taken together, the aforementioned factors explained 81.1 % of the total variance. CONCLUSION: Female college students' intention to abstain from sexual behaviors requires education promoting moderate and conservative positions. The participants' subjective norms concerning sexual behaviors as perceived by friends and parents were also important. The results of this study provide meaningful implications for education of parents, sexual education of female college students, and sexual counseling programs.

Porphyromonas species are closely associated with companion animal periodontitis which is one of the most common diseases in dogs and cats and leads to serious systemic diseases if left untreated. In this study, we evaluated the antimicrobial effects and mode of action of sodium tripolyphosphate (polyP3, Na5P3O10), a food additive with proven safety, using three pathogenic Porphyromonas species. The minimum inhibitory concentrations (MICs) of polyP3 against Porphyromonas gulae, Porphyromonas cansulci, and Porphyromonas cangingivalis were between 500 and 750 mg/L. PolyP3 significantly decreased viable planktonic cells as well as bacterial biofilm formation, even at sub-MIC concentrations. PolyP3 caused bacterial membrane disruption and this effect was most prominent in P. cangingivalis, which was demonstrated by measuring the amount of nucleotide leakage from the cells. To further investigate the mode of action of polyP3, high-throughput whole-transcriptome sequencing was performed using P. gulae. Approximately 30% of the total genes of P. gulae were differentially expressed by polyP3 (> 4-fold, adjusted p value < 0.01). PolyP3 influenced the expression of the P. gulae genes related to the biosynthesis of thiamine, ubiquinone, and peptidoglycan. Collectively, polyP3 has excellent antibacterial effects against pathogenic Porphyromonas species and can be a promising agent to control oral pathogenic bacteria in companion animals.

BACKGROUND: Many students are interested in their appearance and express a strong concern about cosmetics use. However, few studies have reported on cosmetics use in teenagers visiting dermatologic clinics. Recently, there was a report on consumer's behavior regarding cosmetics in Korea, so we attempted to assess this behavior in our clinics. OBJECTIVE: This study aimed to assess behavior regarding cosmetics use in teenagers. METHODS: We conducted a questionnaire survey with 26 questions concerning cosmetics use behavior of teenagers who visited dermatologic clinics and participated in the campaign program. The questionnaire consisted of basic information about the type of cosmetics most frequently used. RESULTS: A total of 269 individuals participated in our survey, consisting of 118 men (43.9%) and 151 women (56.1%). Most participants (92.2%) used cosmetics. The most frequently used skin care and makeup product was sun cream (81.5%) and lip balm/gloss (40.7%). Most participants (80.2%) responded that they use cosmetics daily. This result shows that cosmetics use is common among teenagers. The common influences of starting cosmetics use are friends and neighbors. Teenagers used cosmetics mainly for cosmetic purpose (42.3%), followed by increasing self-regard (35.9%) and improving skin status (19.4%). Seventy-eight teenagers (31.5%) developed side effects after using cosmetics. The most common side effects were contact dermatitis (78.4%). CONCLUSION: This study found that teenagers are becoming a rising consumer in the cosmetics industry. Therefore, we suggest that dermatologist should provide teenagers with appropriate education and management on cosmetics use.

OBJECTIVES: This study aimed to identify the individual and regional characteristics that influence suicidal ideation among the Korean elderly population. METHODS: Using data collected from the 2013 Korea Community Health Survey, a multilevel analysis was performed to establish an understanding of individual behavioral patterns and regional influences on suicidal ideation. RESULTS: Among the 77,407 individuals sampled, 11,236 (14.5%) elderly people over 60 years of age experienced suicidal ideation. Among individual factors, age, frequency of communication with friends, religious activity, social activity, leisure activity, trust in neighbors, subjective stress level, depressive symptoms, and subjective health status were significantly associated with suicidal ideation. The results showed that the lower the regional deprivation level, the higher the suicidal ideation odds ratio. In terms of regional size, the most significant effects were found in rural areas. CONCLUSIONS: This study suggested that suicidal ideation in the elderly is associated with community factors, such as the regional deprivation index, as well as personal factors.
